An interesting feature of the Cook Law Quadrangle's architecture are the corbels in the three walkways between South University and the Quad. A corbel is a projection that helps support the structure above it. The information about the representations of the corbels is taken from Ilene Forsythe's The Uses of Art: medieval metaphor in the Michigan Law Quadrangle, c1993.
For a diagram identifying the location of the corbels, see Location of the Corbels in the University of Michigan Law Quadrangle.
